| Abstract: | The design and operation of tail gas absorption system in Honglin s 270 kt/a sulphur-burning sulphuric acid plant are described.The tail gas absorption system was designed to use ammonia-fertilizer desulphurization process.Tail gas was absorbed by waste aqueous ammonia from ammonia plant in a new tower with two beds,and oxidation and concentration were carried out in the tail gas absorption system of 800 kt/a sulphuric acid plant.After revamping,tail gas absorption system was running well.SO_2 concentration of stack gas was controlled at 100- 300 mg/m~3,with ammonia escaping of 20-50 mg/m~3,SO_2 absorption efficiency of about 85%,process water added into absorption tower of about 2 m~3 /h,and pressure drop across tail gas absorption system of about 0.5 kPa. |
